Abstract

Spiral angel is an important structure parameter of spiral oil wedge sleeve bearing, which produces greater impact on bearing performance. Based on JFO boundary condition, the generalized Reynolds equations considering four slip conditions are established. Using the concept of partial derivatives, stiffness and damping coefficients of sleeve bearing are calculated. The results show that carrying capacity and friction drag of oil film decrease, temperature rise decreases first and then increases, and end leakage rate, stiffness, and damping coefficients generally increase first and then decrease with the increase of spiral angle. The carrying capacity, friction drag, temperature rise, stiffness, and damping coefficients are smaller and the end leakage rate is higher considering wall slip and JFO condition compared with reckoning with no slip and Reynolds boundary condition.

螺旋角对螺旋油楔套轴承性能的影响

螺旋角是螺旋油楔套轴承的一个重要结构参数，对轴承性能影响较大。基于JFO边界条件，建立了考虑四种滑移条件的广义雷诺方程。利用偏导数的概念，计算了套筒轴承的刚度和阻尼系数。结果表明，随着螺旋角的增大，油膜的承载能力和摩擦阻力减小，温升先减小后增大，端部泄漏率、刚度和阻尼系数一般先增大后减小。与无滑移和雷诺边界条件下的计算相比，考虑壁面滑移和JFO条件下的承载力、摩擦阻力、温升、刚度和阻尼系数较小，端部泄漏率较高。

期刊介绍： This comprehensive journal provides the latest information on rotating machines and machine elements. This technology has become essential to many industrial processes, including gas-, steam-, water-, or wind-driven turbines at power generation systems, and in food processing, automobile and airplane engines, heating, refrigeration, air conditioning, and chemical or petroleum refining. In spite of the importance of rotating machinery and the huge financial resources involved in the industry, only a few publications distribute research and development information on the prime movers. This journal is the first source to combine the technology, as it applies to all of these specialties, previously scattered throughout literature.
